It’s not something I follow closely, but every so often, I read posts about the supposed ‘death of the lecture’ (here’s one example and another here) that either argue for or against lecturing. Here’s what I find odd: as a ‘grownup’ scientist (i.e., not an undergraduate in a course), if I went to a seminar, and the speaker were to start to do a whole bunch of interactive shit, I would probably just get up and walk out. At this point, playing ‘Simon says’ isn’t how I want to spend my day.
I realize there’s a lot of self-selection here: outside of the classroom, scientific presentations are given in seminar format, so if you don’t like that format, your odds of sticking with academic science drop. Yet, it’s odd that the lecture is disparaged for one audience (students) and all-pervasive for another (working scientists).
